I just bought four patio chairs at a yard sale with the yellow webbing faded out to a very nice pale lemony yellow EXCEPT for one chair which is still mostly a stronger shade of yellow.  Does anyone know of a way to fade the yellow webbing without damaging it? The webbing is all in good condition so I don't want to replace it if possible.

Maybe leave it out in the sun for a few days until it looked like the others? Edey
